To all whom it may concern:

Be it known that I, TIMOTHY I.

My invention consists in sharpening horse shoes, while attached to the foot, by grinding.

g o, pinch-screw.

In order to sharpen horseshoes by my invention I take up the foot, place the rest B over the calk, then the breast-strap G against the breast; then press the grinding-cylinder A against the other side ot' said calk, holding it in position with the handles I I. By rotating the driving-wheel E the grinding-cylinder A is rotated against the calk, which grinds said calk sharp. The rest or guide B can be raised or lowered a-nd held in -position by pinchscrew o.
